Topographical Study of the Facial Nerve Function
Para clinical REVIEW
You must appreciate the importance of facial injury on the functional level and exploration shall topography.La at three levels:
. Cochleovestibular, is assessing the hearing status, the presence of tinnitus and the notion of imbalance or dizziness.
. Radiology, CT., RML.; Indispensable to assess the state of rock more particularly the three portions of the channel tubes.
. Topographical study of the facial nerve function, numerous test localize the level of facial injury and should be performed early, the more interesting the Schemer test, if this is normal facial nerve injury is below the geniculate ganglion. gustatory test is to determine the taste of two-thirds of the tongue, a problem with the same injury claims at or above the third portion of the channel tubes. antipodean reflex examines the functioning of the muscle of the stirrup, states when an injury is abolished at the third part. functional examination is based on the electrodiagnostic the same should be practiced. electromyography was used early in the needle stimulation. electroneuronografìa currently uses its results more reliable for prognosis are given from fifth to tenth day and especially from fifth to seventh day. A sudden drop in excitability enervation demonstrates rapid and alarming prognosis.
Since 1985 is supported as a reference system for the American Academy of Head and Neck Surgery, HOUSEBRACKMANN classification for evaluation of facial function, the same consisting of six grades:
. Grade 1: normal facial function
. Grade 2: discrete lesion
. Grade 3: moderate injury
. Grade 4: moderately severe injury
. Grade 5: severe injury
. Grade 6: gridlock
TREATMENT
Three are active therapeutic, medical treatment, functional rehabilitation and surgery. They can be used or the circumstances associated clinics facial injury.
MEDICAL TREATMENT
Anti-inflammatory steroid type, dose 1mg/Kg./día, preferably the intravenous route, then the mouth, its use should be early.
Antiviral, acyclovir, can be used by the oral route, its use should be early.
Antiviral, acyclovir, can be used intravenously to obtain high torque and holders serum concentrations of 15 to 30mg / per day which is well absorbed and converted to acyclovir by intestinal and hepatic metabolism.
Vasodilatadores can be used to start the IV and then orally.
B vitamin therapy, it seeks to use its neurotrophic action administering a high dose.
